Description

Technical Field

[0001] The present invention relates to the technical field of unmanned aerial vehicles (UAVs), and in particular to a shock absorbing structure of an UAV. Background Art

[0002] Unmanned aerial vehicles (UAVs) are unmanned aircraft controlled by radio remote control and self-contained programmable controls, or operated completely or intermittently autonomously by an onboard computer. UAVs can be categorized by their application into military and civilian applications. With the rapid development of UAV technology, drones are becoming increasingly intelligent and widespread, and are being actively applied across various industries, facilitating their rapid development.

[0003] When a drone is landing, the bottom of the drone will collide with the ground. Therefore, in order to prevent the bottom of the drone from directly colliding with the ground, a landing bracket is installed at the bottom of the drone. However, most of the existing landing brackets do not have a shock-absorbing effect, resulting in the bracket being damaged due to impact after repeated use. At the same time, most drones need to perform shooting operations, so the shooting device is installed at the bottom of the drone. However, when the drone is running, it will vibrate, affecting the shooting effect. Therefore, the present application provides a shock-absorbing structure for a drone to meet the needs. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a shock absorber for a drone to solve the problem that the existing drone landing bracket has no shock absorption effect and the vibration of the drone affects the use effect of the carried camera original.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A shock-absorbing structure for an unmanned aerial vehicle comprises a body and a shock-absorbing plate, wherein the shock-absorbing plate is movably mounted below the body, a shock-absorbing rod is fixedly mounted on the upper end of the shock-absorbing plate, a center block is fixedly mounted on the upper end of the shock-absorbing rod, a cross movable groove is fixedly mounted on the lower end surface of the body, a first spring is fixedly mounted between the center block and the body and passes through the interior of the movable groove, a sliding rod is fixedly mounted on the interior of the movable groove, connecting blocks are fixedly mounted on the four side surfaces of the center block, the interior of the connecting block is movably connected to a connecting rod, one end of the connecting rod is movably connected to a slider and is movably mounted on the outside of the sliding rod, and a clamping block is fixedly mounted on the lower end of the body.

[0007] In one possible implementation, wings are movably installed on both sides of the body, and fan blades are movably installed on one end of the wing. Storage slots are opened on both sides of the body, and one end of the wing is movably embedded in the storage slot. A lighting lamp is installed at the front end of the body.

[0008] In one possible implementation, a stabilizing plate is fixedly installed at the lower end of the body, pillars are fixedly installed between the four corners of the stabilizing plate and the bottom end of the body, a second spring is fixedly installed inside the pillar, and embedded rods are fixedly installed at the four corners of the shock-absorbing plate, and the upper end of the embedded rod is embedded in the pillar and fixedly connected to the second spring.

[0009] In one possible implementation, the lower end of the body is fixedly connected to a mounting plate, a mounting hole is opened inside the mounting plate, a stabilizing frame is fixedly installed on the lower end of the mounting plate, a clamping plate is movably installed inside the stabilizing frame, a side airbag and a main airbag are fixedly installed between the clamping plate and the mounting plate, a through pipe is fixedly connected between the side airbag and the main airbag, and an air filling port is fixedly opened on one side of the side airbag.

[0010] In one possible implementation, multiple fourth springs are fixedly installed inside the side airbag and the main airbag, a rubber frame is fixedly installed inside the main airbag, the fourth springs are fixedly installed inside the rubber frame, and the interiors of the side airbag and the main airbag are both filled with gas.

[0011] In a possible implementation, a first rotating shaft is fixedly mounted on the lower end of the clamping plate, a second rotating shaft is fixedly connected to the rear end of the clamping block, and the lower end of the first rotating shaft is movably connected to the second rotating shaft through a supporting plate.

[0012] In a possible implementation, a clamping groove is provided inside the clamping block, adjustment rods are movably and symmetrically installed on both sides of the clamping groove, partition grooves are provided on both sides of the clamping groove, and the adjustment rods pass through the interior of the partition grooves.

[0013] In a possible implementation, a clip is symmetrically and movably installed inside the clip groove, a connecting groove is fixedly installed on the side of the clip, and a third spring is fixedly installed between the connecting groove and the adjustment rod.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] First, by setting up a shock-absorbing bracket; a shock-absorbing plate is installed at the lower end of the UAV. When the UAV lands, the shock-absorbing plate first contacts the ground, driving the upper shock-absorbing rod to move upward. Multiple movable connecting rods are movably installed around the upper end of the shock-absorbing rod. One end of the movable connecting rod moves outside the sliding rod through a slider. A buffer spring is installed between the top of the shock-absorbing rod and the UAV, and the elastic effect of the spring is used for buffering and shock absorption.

The shock-absorbing effect is supported by filling the inside of the airbag with gas. At the same time, a spring is installed inside the airbag, which can receive and release the vibration transmitted from the upper mounting plate to prevent the vibration from continuing to be transmitted downward and affecting the use effect of the camera original.

[0017] Third, by setting a camera mounting slot that is easy to use; movable clamps are installed on both sides of the interior of the mounting slot, and the two movable mounting adjustment rods of the clamping slot. When in use, the camera original is placed inside the mounting slot, and the clamping of the camera original is adjusted by turning the adjusting rod. A spring is installed between the front end of the adjusting rod and the clamping piece, which can perform elastic action during clamping to prevent damage to the camera original due to excessive clamping. A rotating rod is installed at the rear end of the mounting slot to adjust the angle during shooting. BRIEF DESCRIPTION OF THE DRAWINGS
